PRODUCT DESCRIPTION

Superb cosmetic condition and excellent working order. As good an example as you could wish to find of this spectacular distortion and reverb unit.

Every one of these is different and this is a wonderful sounding example. It’s fair for us to describe ourselves as Grampian experts as we are now in the process of building a limited number of our own version of this killer effect.

Description

These are increasingly hard to track down, and often have tricky issues to iron out – we’ve found few techs are able to make these sound as they should. This is a chance to obtain one of these remarkable units with our seal of approval.

Far from a one-trick pony, Grampians are things of wonder for anyone who loves rich harmonic distortion, and they have a myriad of uses in the studio – see our main Grampian pages and previous Grampian blog post for more on these machines. From Lee Scratch Perry to Pete Townshend of the Who, these unprepossessing grey boxes are responsible for a great deal of historic sonic mayhem.

Jack sockets have been switched to conventional quarter inch (the originals are short “B” type sockets – very easy to damage by inserting a regular jack) and the all-important pilot light is functioning as it should.

Grampian User Tips

Some useful info for using a Grampian 363 in a modern studio set up. By no means a full user guide, but this should help you integrate this old piece of kit into a modern set up.

TESTIMONIALS

“I’ve bought a number of items from Soundgas recently, and have been really impressed with their service. It takes the stress out of buying vintage gear to know it’s been properly (and faithfully) serviced or restored. Their after-sales service has also been exemplary. Highly recommended.”

David Wrench

"Soundgas offer a great service, sourcing esoteric gear that works great."

Tom Rowlands - Chemical Brothers

"Excellent equipment, wonderful service. I fully recommend Soundgas to anyone in the vintage gear market and I will definitely be a return customer. The gear itself was exactly as advertised and in great condition."

Hallam Kite

"Just received my Roland RS 505 Paraphonic! Thanks so much - arrived very promptly, well packaged, in great condition and sounds amazing! Best seller."

Koko Hiras

"Soundgas provided the absolutely top service in terms of item quality as well as service and communication. Shipping was fast, packing was top notch. These people deserve the best reputation they already have. Many many thanks, guys."

Dupille Luc

"Finally, a company that tracks down all those brilliant curiosities that bring so much character and personality to a studio."

Matthew Herbert

"When you are spending big money of vintage gear it's nice to have the confidence of impeccable service, sales and support... some of the best in the industry! Impeccable people, incredible equipment… my poor poor fiancé"

James DLR - Sofa Sound/Metalheadz

“I have bought two Moog synths from Soundgas over the past year, and I cannot say enough wonderful things about their selection of vintage products, the level of service, diligent responses to email, and expedient shipping with copious protective packaging. Soundgas is an impressive operation. My synths also sound amazing! These folks have made my vintage keyboard dreams come true in short order!”

J Yates

"Still in shock! Can not believe how good the seller is. This product was inspected, and shipped from the UK to the USA quicker than orders from my home state. Highly recommend these guys."

Thomas Tedesco

"The packing job to get it over to the US was superb, and the sound and performance of my Space Echo exceeds all of my expectations. I hope to do business with Soundgas again in the future. Many thanks!”

Rhett Daily

“Imagine the perfect eBay.... with everything you never knew you wanted… and you can rest assured that your vintage and rare wobbly sound device will turn up on time and in one piece and possibly in even better condition that when it left the workshop. Soundgas - literally amazing."

Josh Lloyd-Watson & Tom McFarland - Jungle

“The perfect place to hear, learn about and then buy your most wanted piece of vintage music gear! I've not only managed to buy a rare piece of equipment I really wanted, but I have the guarantee it's been serviced, and I got it from people who are clearly passionate and knowledgeable about what they do, as well as super friendly and responsive by email. Thoroughly recommended!”

Colleen / Cécile Schott

"DREAM. COME. TRUE. My music has taken me around the world a few times...and if you are like me and absolutely adore vintage gear...Soundgas is the stuff of LEGENDS. It's the shop that people like us search for our whole lives- fantastic and rare selections, and the technical know-how to repair and or mod these vintage items to get them into shape to flow with your modern setup."

Tom Gossin

“I purchased a completely overhauled vintage valve Binson Echorec 2 T7E modified with varispeed, wet-only output, and a new paint job from Soundgas in early 2018. Tony and his team did an amazing job during every step of the purchase”

Matt Morton

"Soundgas has an unbelievable selection of the cool, old stuff that’s hard to find. Tony knows his stuff and goes out of his way to make sure the transaction is a smooth one. Thanks guys!"

Tucker Martine - Flora Recording

“If you are a vintage audio gear head then this is the place you have been looking for all your life. Pretty much any piece of classic or obscure kit that you are after is available here... But the clincher for me is that the gear they sell has been restored by their top techs (unless otherwise noted) which is really very important when dealing with, for example, synths from 30 years ago.”

Lincoln Barrett / High Contrast

"Packed with love and care. A stampede couldn't have crushed this thing. Works great and sounds like a dream. I love you Soundgas."

Ben Van Vlissingen

“The Space Echo made its way to me - it looks and sounds beyond dreams, thanks guys for your great service and communication.”

Julius Bonson

“If not a new language, then at least a very challenging, old dialect that will take me some time to assimilate. I’ve been waiting a long time for the challenge. Thank you @soundgasltd, she’s a beaut...and nobody prepares and packs like you fine folks.”

Justin Meldal-Johnsen
